If the whites are getting off white or yellowish bluing will do the trick. You just dilute it in water and add to the rinse cycle. It can be found in the laundry detergent section of the grocery store (you might want to ask someone there because it is a small bottle and not the easiest to find). This is the one I bought:

The modern version of bluing is called an optical brightener. It absorbs UV light and fluoresces blue (thus offsetting any yellowish tint the cloth may have picked up).

Some blue fluorescent dyes:

You might also be able to mix fabric medium with a phosphorescent paint:

hydrogen peroxide, bleach, and sand blasting it (assuming they're made of cotton)
